Here, we report the poisoning case of 10 cows. Several distinct clinical signs such as convulsion, excessive salivation, circling, lateral recumbency, and death were observed. Necropsy and histopathological examination did not reveal any significant abnormal findings. Moreover, no bacteria or viruses were detected in tissue, blood, and feeding food. However, endosulfan was detected from the stomach contents and microbials. Our results strongly suggest that death of cows may be closely associated with endosulfan poisoning.

Parotid gland swelling in association with general anesthesia is an unusual complication. Benign postoperative parotid swelling should be recognized as a noninfectious, self-limiting process occurring immediately after surgery. This enlargement is non-tender, rubbery in consistency, without crepitus, and may be accompanied by variable salivation. The mechanism of the occurrence remains unknown, but two factors most frequently associated with this phenomenon appear to be physical stimulation or manipulation of the airway or coughing and/or straining. We report bilateral parotid gland swelling in a middle-aged man after surgery under general anesthesia.

OBJECTIVES: Daytime drowsiness or sedation and changes in night sleep are commonly seen in patients treated with clozapine. There is, however, very limited informatio on their degree and nature during the course of treatment. The purpose of this study was to understand the sleep patterns in chronic schizophrenic patients with clozapine treatment over a period of 24 weeks. METHOD: The sleep pattern was evaluated using a set of 5-point scale questionnaire, to record subjective impressions of the night sleep induction, maintenance and quality, and daytime drowsiness and fatigue. In addition, unusual experiences associated with night sleep were recorded. The sleep questionnaire was repeatedly administered at baseline and at 1, 2, 4, 8, 12 and 24 weeks of drug treatment. At present, data on 12 patients has been collected. RESULTS: All the components of night sleep were significantly improved in th 1st through the 12 th week after treatment with clozapine. Daytime drowsiness was significantly higher in the 1st to the 2nd week after the treatment and fatigue was also significantly higher in the 1st to the 4th week after the treatment. Eight patients experienced noticeable increases in salivation during night sleep, and of these, one also reported frequent nocturnal urination and even enuresis. However, all these adverse factors did not affect the major sleep patterns. CONCLUSIONS: These finding suggest that the beneficial effects of clozapine on night sleep might last much longer than the undesirable effect of daytime drowsiness and fatigue. In other words, tolerance of the hypnotic action of clozapine might develop late and tolerance of the daytime drowsiness and fatigue might be evident earlier.

Gastroesophageal reflux disease (GERD) and sleep disturbances are both common health problems. There is a significant association between disturbed sleep and GERD, and this may be bidirectional. Sleep disorders may induce gastrointestinal (GI) disturbances, while GI symptoms also may provoke or worsen sleep derangements. Reflux of gastric acid is a less frequent event during sleep, however, acid clearance mechanisms (including swallowing, salivation and primary esophageal motility) are impaired during sleep resulting in prolongation of acid contact time. Nighttime reflux can lead to sleep disturbance and sleep disturbance may further aggravate GERD by prolonged acid contact time and heightened sensory perception. This may facilitate the occurrence of complicated GERD and decreased quality of life. However, the interplay between sleep problems and GERD is complex, and there are still relatively limited data on this issue. Further investigation of sleep-related GERD may identify common pathophysiological themes and new therapeutic targets.

Tri- and tetra-cyclic antidepressants are known to cause dry mouth among other several major complications. The present study was designed to compare the degree of reduced salivation due to antidepressants and to explore whether intracellular calcium-increasing agents ameliorate the salivation. Effects of antidepressants and agents increasing intracellular calcium on the cholinergic submandibular secretion and blood flow induced by the chorda stimulation or intra-arterial acetylcholine were observed in anesthetized cats. Effects of antidepressants and calcium-mobilizing agents on K+ efflux were also observed in excised gland slices. The results obtained were as follows: 1. Salivary secretion in response to the chorda stimulation (3 V, 20 Hz, 1 msec) was significantly attenuated by antidepressants in a dose-dependent manner, whereas the blood flow was not affected. 2. Salivary secretion and increased blood flow evoked by intra-arterial acetylcholine (20 microgram/kg) were markedly diminished by antidepressants, the magnitude of which was amitryptyline>imipramine >mianserin in order. 3. Cholinergic salivation was significantly decrease by cyclopiazonic acid, a calcium pump inhibitor of the endoplasmic reticulum, or by BAPTA/AM, a specific intracellular calcium chelator. 4. Caffeine and ryanodine potentiated the cholinergic salivation and ameliorated the depressed salivary secreation due to antidepressants. 5. Calcium ionophore A 23187 ameliorated the depressed salivation due to antidepressants. 6. Antidepressants inhibited the K+ efflux, which were restored by caffeine or A 23187. These results suggest that the depressed salivary secreation due to antidepressants is ameliorated by increasing intracellular calcium levels.

PURPOSE: The purpose of this study was to investigate effects of Oral Function Improvement Exercises on salivation, xerostomia and halitosis in elderly people. METHODS: The participants in the study were 48 female community-dwelling elders in D city. The Oral Function Improvement Exercises were given 3 times a week, for a total of 24 times from August to October 2011. Spitting method, Visual Analogue Scale, and halimeter (mBA-21) were used to evaluate the effects of Oral Function Improvement Exercises on salivation, xerostomia, and halitosis. The data were analyzed using chi2-test and t-test with the SPSS program. RESULTS: The experimental group had significantly better salivation, and less xerostomia and halitosis than the control group. CONCLUSION: The results indicate that Oral Function Improvement Exercises were effective for salivation, xerostomia and halitosis in the elders. Therefore, it was suggested that Oral Function Improvement Exercise are applicable in a community nursing intervention program to improve the quality of life for elders.

Muscarinic acetylcholine receptors (mAChRs), including M1-M5 subtypes, are classic receptors in regulating water, ion, and solute transport in salivary gland. Our work focuses on the studies on the expression pattern and function of mAChR in the submandibular gland (SMG), and the underlying mechanism involved in the mAChR-regulated secretion, together with the effect of parasympathectomy on the salivary secretion. Microvascular autotransplantation of SMG into the temporal fossa provides a continuous and endogenous source of fluids, and is currently an effective method for treating severe keratoconjunctivitis sicca. By using RT-PCR, Western blotting, and immunofluorescence, our data demonstrated that the expression of M1 and M3 subtypes were decreased in latent period in rabbit SMG autotransplantation model, whereas carbachol stimulation promoted the salivary secretion, as well as M1 and M3 expressions. By contrast, mAChRs were hypersensitive in epiphora SMGs, whereas atropine gel and botulinum toxin A application significantly inhibited the hypersecretion in both animal models and patients. Furthermore, the possible intracellular signal molecules involved in the mAChR-modulated salivary secretion were explored. Activation of mAChR upregulated the expression of aquaporin 5 (AQP5), the main transporter that mediated water secretion through transcellular pathway, and led to AQP5 trafficking from lipid rafts to non-lipid microdomain. Extracellular signal-regulated kinase 1/2 (ERK1/2) was involved in the mAChR-regulated AQP5 content. mAChR activation also modulated the expression, distribution, and function of tight junction proteins, and increased paracellular permeability. ERK1/2/β-arrestin2/clathrin/ubiquitin signaling pathway was responsible for the mAChR-regulated downregulation of tight junction molecule claudin-4. Cytoskeleton filamentous actin (F-actin) was also involved in the distribution and barrier function of epithelial tight junctions. Besides, endothelial tight junctions were opened by mAChR agonist-evoked salivation in the mice. Furthermore, parasympathetic denervation increased resting salivary secretion in the long terminrats and minipigs. Taken together, our work demonstrated that mAChR regulated saliva secretion via transcellular and paracellular pathways in SMG epithelium as well as tight junction opening in SMG endothelium. Modulation of mAChR might be a promising strategy to ameliorate SMG dysfunction.

Organophosphate fungicides include edifenphos, iprobenfos and tolclofos-methyl. Edifenphos inhibits cell wall synthesis by reduction in chitin synthase activity and inhibits the action of acetylcholinesterase. Thus, exposure to this chemical results in excessive salivation, lacrimation, urination, defecation, gastrointestinal motility and emesis symptoms, just like other organophosphate insecticides. Although edifenphos is an organophosphate fungicide, it is the only agricultural chemical which inhibits the action of pralidoxime and atropine, an activity which in turn, inhibits treatment. Thus, we have to treat these cases as soon as possible with atropine and pralidoxime, using the same approach as used for exposure to other organophosphate insecticides. In this report we evaluate the results of treatment of 4 patients who were intoxicated by fungicides (3 cases with edifenphos and 1 case with iprobenfos).

BACKGROUND: The optimal time to remove the laryngeal mask airway (LMA) at the end of surgery is still a matter of controversy. The purpose of this study was to compare the incidence of complications associated with the removal of the LMA from the deeply anesthetized and from the awake patient. METHODS: The LMA was used in 120 adults undergoing general elective lower abdominal or extremity surgery. The patients were randomly assigned to two groups. In 60 patients the LMA was removed by the anesthetist with the patient deeply anesthetized in the operating room. In the other 60 patients it was removed by the anesthetist when the patient responded to verbal commands in the operating room. Any airway complications occurring within 15 minutes of LMA removal were recorded. These complications included coughing, biting, retching, vomiting, excessive salivation, airway obstruction and laryngospasm. RESULTS: Groups were similar in age, weight, and duration of surgery. Airway complications associated with LMA removal were noted in fourteen patients. Airway complications occurred in six patients who had their LMA removed during deep anesthesia, and in eight patients who under went removal of their LMA on awakening. In the anesthetized group, there were four kinds of airway complications in six patients (retching, excessive salivation, airway obstruction and laryngospasm). In the awake group, eight patients experienced six kinds of airway complications (coughing, biting, vomiting, excessive salivation, airway obstruction and laryngospasm). There was no significant difference between the two groups in the incidence of complications after removal of the LMA. CONCLUSIONS: Removal of the LMA under deep anesthesia had no advantage compared to removal from awakening patients in terms of complications in adult.
